WebSponges have the ability to reproduce sexually and asexually. Explain: True. Asexually by budding, gemmules or fragmentation. Sexually by the 'male' sponge would release sperm into the water, which would travel and then enter a 'female' sponge. After fertilization in the sponge, a larva is released into the water. Webfunction in sponges. In sponge: Water-current system …and capture food; and the oscula, openings through which water is expelled (excurrent system).

WebFeb 28, 2024 · The second crucial cells in sponges are called amoebocytes (or archaeocytes), named for the fact that they move throughout the mesohyl in an amoeba-like fashion. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain … Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of sponges that contain a central flagellum, or cilium, surrounded by a collar of microvilli which are connected by a thin membrane. They make up the choanoderm, a type of cell layer found in … See more Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges. See more Choanocytes bear a superficial resemblance to Choanoflagellates. Molecular phylogenies indicate that choanoflagellates and metazoans are sister groups. One can … See more By cooperatively moving their flagella, choanocytes filter particles out of the water and into the spongocoel, and out through the osculum. This improves both respiratory and … See more • Choanocytes See more to the wingless a more arresting phenomenon

WebFunctional features Feeding and digestion. The Porifera are primarily filter feeders, utilizing food particles suspended in the water and captured by the choanocytes.Food particles … WebA sponge's body is hollow and is held in shape by the mesohyl, a jelly-like substance made mainly of collagen and reinforced by a dense network of fibers also made of collagen. The inner surface is covered with choanocytes, cells with cylindrical or conical collars surrounding one flagellum per choanocyte. WebMar 11, 2024 · Choanocytes are specialised cells that line the choanocyte canals and feature a collar of flagella that generates a current to trap food particles. The size and structure of the canals, as well as the quantity of choanocytes present in the sponge’s body, determine the efficacy of its feeding system. potato knishes for sale online
